Digital Rotational Viscometer

The NT 126 & 127 series viscometers are commonly used to measure viscosity (also called apparent viscosity) of Newtonian or non-Newtonian materials at specified rotational speeds with selected spindles. High polymer materials such as coatings, inks and adhesives, as well as resins and emulsions, are mostly non-Newtonian liquids. They exhibit different rheological properties under different shear rates (related to rotational speed and spindle geometry).

To compare rheological properties of different materials in coatings and related industries, the common method is to measure shear thinning (thixotropy index) and thixotropy: The degree of shear thinning is indicated by viscosity reduction as rotational speed increases. Thixotropy can be evaluated by comparing viscosities during speed ramp-up and ramp-down, viscosity recovery, or viscosity values before and after high-shear treatment. High-shear treatment simulates the shearing force during paint application. The viscosity behavior measured after high shear reflects the paint characteristics immediately after application. We supply different types of rheometers for materials with varied rheological behaviors. Operators can set custom measurement programs for different requirements (e.g. automatic shear rate sweeping). With the supporting professional software, material rheological properties can be fully analyzed, including simulation of material performance under different application conditions.
